Automotive exhaust system catalytic converter for Volkswagen Passat 1.8T old

Carbon monoxide (CO) → Carbon diox

Product introduction

Premium catalytic converter for The Volkswagen Passat 1.8T old，This product we use high-quality raw materials 409 stainless steel, and with high flow ceramic carrier, to help each car can purify exhaust gas, reduce fuel consumption, improve power, and extinguish engine failure lights!

First, power system upgrade

ECU tuning (brushing)

Benefits: Optimized fuel injection, ignition timing, and turbine pressure for increased horsepower, torque, and throttle response, potentially improving fuel efficiency (depending on driving habits).

Note: Reliable procedures should be selected to avoid over-squeezing engine life; Some extreme tuning may cause hardware wear.

Intake/exhaust system modification

High Flow Intake Style/Intake Kit: Increase intake efficiency and increase turbine response.

Exhaust head/mid-tail segment: Reduces exhaust back pressure, releases power potential and may improve sound.

Note: need to match the ECU tuning, otherwise the fault code may be triggered; Some modifications may affect the annual inspection.

Second, the control of the improvement

Suspension upgrade

Short spring/Hank shock absorber: reduce the body center of gravity, improve bending stability;

Enhanced anti-roll bar: reduces roll and enhances control accuracy.

Note: Excessive lowering of the body may affect passability, and hard suspension may sacrifice comfort.

Tire/hub upgrades

High performance tires: improve grip and shorten braking distance;

Lightweight wheels: reduces unsprung mass and optimizes acceleration and steering response.

Third, safety and braking

Brake system upgrade

High performance brake pads/scribing brake discs: improve braking efficiency and heat resistance;

Multi-piston caliper set: Enhanced braking force for intense driving.

Note: The wheel size should be matched to avoid interference.

Chassis reinforcement (top bar, chassis tie rod)

Improve body rigidity, reduce bending deformation, enhance control confidence.

Fourth, functional optimization

Cooling system strengthening

Intercooler/water tank upgrade: Improved heat dissipation to prevent turbine power loss due to high temperature.

Note: Especially important for long periods of intense driving or high power modifications.

Electronic equipment installation

Turbine pressure gauge/oil temperature gauge: real-time monitoring of engine status;

Reverse image/radar: Improve the convenience of older models.

5. Precautions

Compliance: Modifications must comply with local regulations (such as exhaust noise, lighting, etc.) to avoid affecting the annual inspection.

Accessories compatibility: Older models need to pay attention to component compatibility (such as sensor interfaces, installation space).

Cost and maintenance: Modifications may increase maintenance costs (such as high-performance brake pads wear faster).

Insurance impact: Some modifications need to be reported to the insurance company, otherwise it may affect the settlement of claims.
